` INTERNAL-'COMBUSTION ENGINE.

To allwhom t nay concer/LL' j Be it known that I, FREDERIC" W. SLACK,

. a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certam'newa and useful Improvement in Internal-Coin bustion Enginesfof which the following 1s a full, clear, and exact description.

This invention relates to internal combustion engines and has particular reference to engines of the -Vtype, although not necessarily confined to that type.

parts thereforfor oil'pumping purposes.

A, still further object is to form the incasing and supportingparts for the combined distributer drive and oil pump sopas to constitute a support for the spark control and throttle shifting members.

The invention may be briefly summarized as consisting in certain novel details of construction and combinations and arrange-A ments vof parts which will be described in the specification and set forth Ain the appended claims..

In the accompanying sheet of drawings, Figure 1 is a side view of the rear portion of an internal combustionengine ofthe V- type,showing conventionally by dotted lines part of the oiling system, this view representing an engine of a motor vehicle with usual throttle and spark controlllng meinbers; Fig. 2 is a view" partly in elevation vand vpartly in vertical section taken substanalong the line 2 2 of Fig. 1,'looking tiall lie direction indicated by the arrows;

int

`and Fig. 84 is a sectional plan'view of the distributer drive and oil pump, the section l being taken substantially along the line 3-`3 Specication of Letters Patent.

Patented Feb. 15,1921.

Application led April 15,' 1918. Serial No. 228,519.

' of Fig. -2 looking in the direction indicated by the arrows, parts being broken away.

Referring now tothe drawings, 10 represents the rear part of the crank -casing of an represents two of the c linders, the engme here shown being pre erably ofthe V- type. In Fig. 1, 12 represents the center line ofthe steering-column through which extendspthe usual throttle and sparkcontrolling posts or shafts vwhich shift respeccylinders. This shaft has a gear 16 which i rotates a second gear 17 on a vertical shaft 18, this shaft 18 being utilized in accordance 4 with the present invention to drive the comblnedtpump and distributer driving gears. The lower'part of thls shaft usually extends downward to the lower part of the engine to drive .an auxiliary part which forms no part ofl this' invention. y

Iny an engine of the V-type whose cylinders are at fairly acute angle, such as 60, in Orderthat the distributer may be accommodated in the space between the cylinders, the distributer is desirably displaced from Moron. CAN

- engine, such. as used on-motor vehicles, and

the shaft 18 toward or directly above the driving shaft 15, and for that reason the shaft 18 instead of being carried directly up to the distributer is provided a short distance above the gears 16, 17, with a gear 19 which meshes with a similar gear 20 secured to a vertical shaft 21 which 1s coupled to the rotary member of the distributer of the 1gn2it-)l1on system, the distributer being shown at The utilization of the two shafts 18 and 21 displaced with respect t each other and connected by gearsr enables me tol use these gears and inclosing parts for other purposes than the mere driving of the distributer, namely, as an oil pump and for an additional purpose to be described.` To this end ety the gears 19, 20 are made in the form of spur gears suitable for use as a gear oil pump, and I inclose these gears in a casing composed of a lower part or body portion 22, which is suitably mounted and secured to a part 23 of the engine casing, and of an upper part or cap 24. The top part 24 of the casing has an upward extension 25 which vinclos'es the shaft 21 and the coupling to the rotary member of the distributer, and constitutes a support for the distributer.

At the upper part or cap y24 of the casing is the oil inlet 26 and the oil outlet 27 which are connected to the oiling system, a part of which I have indicated in Fig. 1 by the dotted lines to which arrows have been a'pplied to show the course of oil circulation. The precise details ofthe oiling system, the rarrangement of piping, etc., is immaterial tomy invention, and to avoid eonfusiononly a part of the oiling system is shown, and that in a conventional manner.

In addition to utilizingv the parts as an oil pump and distributer drive, the structure of which the cap or'casing member 24 is a part is utilized not only to support the distributer as previously explained, but also as a supporting bracket for the throttle and spark control shafts and levers. 'Io this end the cap 24 is provided with an arm 28 with a bearing boss 29 and the upstanding part 25 of the cap is provided with a bearingboss 30 in which is journal'ed a shaft 31 carrying a surrounding sleeve or hollow shaft 32. The former, z'. e., the shaft 31 is provided with a lever 33 to which the throttle controlling rod 14 previously mentioned is connected. At the inner end of shaft 31 is an arm 34 against which is pressed by a spring 35 a lever 36 which is also on the shaft 31, but loose thereon, this lever 36 having a connection with the throttle and also being designed to be turned independently' of the shaft 31 by the foot accelerator. The sleeve 32 carries at its outer end a lever 37 to which is conuter drive, an oil pump, and supportingV bracket for throttle and spark control menibers.

As previously stated, my invention while having special utility in a V-type engine, may in whole or in part ,be used to advantage on other types of engines, such as engines having the cylinders in a single row. Furthermore, I wish it to be understood that the details of construction and arrangement may be modified considerably without constituting adeparture from the spirit and scope of my invention in its broad aspects.

Having described my invention, I claim:

1. In an internal combustion engine having an oil circulating system and a distributer for ignition purposes, a pair of distributer drive shafts, and a pair of gears connecting said shafts, said gears being utilized for oil distributing purposes.

2. In an internal combustion engine having/ an oil circulating system and a distributer for ignition purposes, a pair of distributer drive shafts off-set from each other, gears connecting said shafts, and a casing inelosing the gears and forming with the latter an oil pump.

y 3. In an internal combustion engine having an oil circulating system and a distributer for ignition purposes, a pair of distributer drive shafts off-set from each other and one geared to an appropriate part of the engine so as to be driven, and the other connected to the distributer, a .pair of-gears connecting said shafts, and an inclosure for the gears forming with the latter an oil pump.

4. In an internal combustion lengine having an oil circulating system and a dlstributer for ignition purposes, a pair of off-set vertically disposed distributer drive shafts, a horizontal shaft geared to one of said shafts for driving purposes, and the other of said off-set shafts being connected to the distributer, a pair of spur gears connecting said off-set shafts, and a casing inelosing said gears and formingy therewith an oil 5.
